The title of Emmanuel Eze’s final, posthumously published book uses the words “reason” and “rationality” in a manner that might suggest they are interchangeable. I would like to suggest that we not treat them as the same, but rather tease out a difference in emphasis and reference between the two. In African philosophy, the problem of reason is really two separate problems, the first of which I will call the “problem of reason” (that is, the question of whether there are diverse forms of reason or only one universal form) and the second the “problem of rationality” (that is, the question of whether everyone has the capacity to deploy reason past what mimicry or programming makes possible). Both of these problems are addressed by Eze’s schema for forms of reason. He identifies several forms, but focuses on “ordinary reason”, which allows all the other forms to operate. Ordinary reason also makes rationality possible, that is, the culturally specific yet emergent way of navigating forms of reason. Reason is necessarily diverse, because its multiple forms are deployed differently by different rationalities.

There are a number of proposals as to exactly how reasons, ends and rationality are related. It is often thought that practical reasons can be analyzed in terms of practical rationality, which, in turn, has something to do with the pursuit of ends. I want to argue against the conceptual priority of rationality and the pursuit of ends, and in favor of the conceptual priority of reasons. This case comes in two parts. I first argue for a new conception of ends by which all ends are had under the guise of reasons. I then articulate a sense of rationality, procedural rationality, that is connected with the pursuit of ends so conceived, where one is rational to the extent that one is motivated to act in accordance with reasons as they appear to be. Unfortunately, these conceptions of ends and procedural rationality are inadequate for building an account of practical reasons, though I try to explain why it is that the rational pursuit of ends generates intuitive but misleading accounts of genuine normative reasons. The crux of the problem is an insensitivity to an is-seems distinction, where procedural rationality concerns reasons as they appear, and what we are after is a substantive sense of rationality that concerns reasons as they are. Based on these distinct senses of rationality, and some disambiguation of what it is to have a reason, I offer a critique of internalist analyses of one’s reasons in terms of the motivational states of one’s ideal, procedurally rational self, and I offer an alternative analysis of one’s practical reasons in terms of practical wisdom that overcomes objections to related reasons externalist views. The resulting theory is roughly Humean about procedural rationality and roughly Aristotelian about reasons, capturing the core truths of both camps.

David Papineau presents a controversial view of human reason, portraying it as a normal part of the natural world, and drawing on the empirical sciences to illuminate its workings. In these six interconnected essays he discusses both theoretical and practical rationality, and shows how evolutionary theory, decision theory, and quantum mechanics offer fresh approaches to some long-standing problems.

Contending that only a normative theory of rationality can be adequate to the complexities of the subject, this book explains and defends the view that rationality consists of the intelligent pursuit of appropriate objectives. Rescher considers the mechanics, rationale, and rewards of reason, and argues that social scientists who want to present a theory of rationality while avoiding the vexing complexities of normative deliberations must amend their perspective of the rational enterprise.

Ecological rationality is a concept important to most environmental and natural resources policy and to much policy-relevant literature and research. Yet ecological rationality as a distinctive form of reason can only be understood and appreciated in the context of a larger body of work on the general concept of rationality. In particular, Herbert Simon’s differentiation between substantive and proceduralrationality and Paul Diesing’s specification of forms of practical reason are useful tools in mapping and defining ecological rationality. The significance and characteristics of ecological rationality suggest that it is a fundamental kind of reason, having precedence over others.
